We had fun videotaping part of a lesson from a different camera angle. My student and I sat in front of our separate pianos, collaborating on two Bach Inventions. (Number 4 in D minor and number 13 in A minor)
In the first segment, my pupil is playing through the d minor Invention, mostly on her own, with some teacher input and demonstration.
The second part offers a slow rendering of the A minor Invention as a duet between student and teacher–the playing is intentionally behind tempo to flesh out the main subject as it weaves between the right hand and left.
I’ve included my separate performance of this composition that is in tempo.
All the two-part Inventions have a dialog or counterpoint between voices that require the performer’s attention to detail.
